Abstract
We report single transverse and longitudinal mode operation of an all solid-state orange laser pumped at 821 nm. Oscillation at 607 nm by avalanche upconversion in Pr, Yb:BaY₂F₈ pumped by a Ti-Sapphire laser at 821 nm is obtained with a threshold as low as 570 mW. A maximum output power of 12 mW is obtained for a pump power of 2.5 W.
